BACKGROUND Technical Field

The present disclosure relates to transmission methods and devices in wireless communication systems, and in particular to a scheme and a device for measurement in wireless communication.

Related Art

Application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios have different performance demands on systems. In order to meet different performance requirements of various application scenarios, the 3^(rd) Generation Partner Project (3GPP) Radio Access Network (RAN) #72 plenary session decided to conduct the study of New Radio (NR), or what is called fifth Generation (5G). The work Item (WI) of NR was approved at the 3GPP RAN #75 plenary session to standardize the NR. Compared with the existing LTE systems, 5G NR has an outstanding feature of supporting more flexible Numerologies, which includes Subcarrier Spacing (SCS) and Cyclic Prefix (CP), and more flexible frame structures, such as of mini-slot, sub-slot and slot aggregation. With such flexible numerologies and frame structures, various new business requirements will be better satisfied, especially in highly diversified vertical industries.

In response to rapidly growing Vehicle-to-Everything (V2X) traffic, 3GPP has started standards setting and research work under the framework of NR. Currently, 3GPP has completed planning work targeting 5G V2X requirements and has included these requirements into standard TS22.886, where 3GPP identifies and defines 4 major Use Case Groups, covering cases of Vehicles Platooning, supporting Extended Sensors, Advanced Driving and Remote Driving. At 3GPP RAN #80 Plenary Session, the technical Study Item (SI) of NR V2X was approved.

SUMMARY

A stricter payload balance control is a significant characteristic that differentiates V2X from traditional cellular network, since effective payload control can reduce the probability of business conflicts and improve transmission reliability, which are critical factors for successful V2X. In LTE V2X system, however, a measurement mechanism for payload control is designed based on a single Numerology, namely, 15 kHz SCS, normal length of CP and 1 ms of subframe length, making it impossible to meet the requirement of more flexible Numerology of 5G NR V2X.

Embodiment 3

Embodiment 3 illustrates a schematic diagram of an embodiment of a radio protocol architecture of a user plane and a control plane according to one embodiment of the present disclosure, as shown in FIG. 3 . FIG. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture of a user plane and a control plane. In FIG. 3 , the radio protocol architecture between a first-type communication node (UE) and a second-type communication node (gNB, eNB or RSU in V2X), or between two first-type communication nodes (UE) is represented by three layers, which are a layer 1, a layer 2 and a layer 3, respectively. The layer 1 (L1) is the lowest layer and performs signal processing functions of various PHY layers. The L1 is called PHY 301 in the present disclosure. The layer 2 (L2) 305 is above the PHY 301, and is in charge of the link between the first-type communication node and the second-type communication node, and a link between two first-type communication nodes (UEs) via the PHY 301. In the user plane, L2 305 comprises a Medium Access Control (MAC) sublayer 302, a Radio Link Control (RLC) sublayer 303 and a Packet Data Convergence Protocol (PDCP) sublayer 304. All the three sublayers terminate at the second-type communication node of the network side. Although not described in FIG. 3 , the first-type communication node may comprise several higher layers above the L2 305, such as a network layer (e.g., IP layer) terminated at a P-GW of the network side and an application layer terminated at the other side of the connection (e.g., a peer UE, a server, etc.). The PDCP sublayer 304 provides multiplexing among variable radio bearers and logical channels. The PDCP sublayer 304 also provides a header compression for a higher-layer packet so as to reduce a radio transmission overhead, provides security by encrypting a packet, and provides support for first-type communication node handover between second-type communication nodes. The RLC sublayer 303 provides segmentation and reassembling of a higher-layer packet, retransmission of a lost packet, and reordering of a data packet so as to compensate the disordered receiving caused by HARQ. The MAC sublayer 302 provides multiplexing between a logical channel and a transport channel.

The MAC sublayer 302 is also in charge of HARQ operation. In the control plane, the radio protocol architecture of the first-type communication node and the second-type communication node is almost the same as the radio protocol architecture on the PHY 301 and the L2 305, but there is no header compression for the control plane. The control plane also comprises a Radio Resource Control (RRC) sublayer 306 in the layer 3 (L3).
